摘要

本文报道了一种工作频率为2.4 GHz的紧凑型四端口四元多输入多输出(MIMO)天线。得到的频率带宽为1.1 ~ 5.3 GHz，适用于WLAN/WiMAX和IoT应用。基板的整体尺寸为30×70×1.6 mm3。天线单元覆盖面积为30×20 mm2，共面接平面面积为30×50 mm2。为了减少元件之间的相互耦合，达到良好的隔离效果，在天线的背面采用了寄生元件。在2GHz时获得的最大隔离度为- 20 dB。工作频率为2.4 GHz时，峰值增益为4.1 dB。采用hfss14对所提出的紧凑平面四元MIMO天线进行了设计和仿真。

A compact wideband staircase-shaped four-element MIMO antenna for WLAN, L-band and S-band applications

In this paper, a compact quad-port four-element multiple input multiple output (MIMO) antenna operating at 2.4 GHz is reported. The frequency bandwidth is obtained as 1.1–5.3 GHz and is suitable for WLAN/WiMAX and IoT applications. The overall dimension of the substrate is 30×70×1.6 mm3. The area covered by antenna elements and the coplanar ground plane are 30×20 mm2 and 30×50 mm2 respectively. To reduce mutual coupling between the elements and achieve good isolation, parasitic element is used at the back of the antenna. The maximum isolation obtained is −20 dB at 2GHz. The peak gain is obtained as 4.1 dB at operating frequency 2.4 GHz. The proposed compact and planar four element MIMO antenna is designed and simulated by using HFSS 14.
